  • a 10% master batch of each antibiotic dry-mixed with PLA was prepared, then extruded with a LEISTRITZ ® lab twin -screw extruder after which, the extruded strands were pelletized.
  • the three-antibiotic-containing filament was supplied to the extrusion nozzle of a STRATASYS ® MOJO ® FDM ® 3D printer to print replicate test coupons at an extrusion temperature of 170° C, each coupon having the physical dimensions of a diameter of 25 mm and a thickness of 2.5 mm, with one surface having a "shiny” appearance and the other surface having a “matte” appearance.
  • the control coupons for this study were taken from the batch of control coupons produced in Example 1.
